摘　　要：采用ANSYS软件建立了单层偏心框架实体仿真模型,充分考虑混凝土结构开裂后刚度的退化,输入多维地震动进行弹塑性反应分析,得出调节各柱纵向配筋率减小结构平扭耦联反应的方法,以供类似工程相关问题的研究参考。The study presents the inelastic seismic response as an emulative model of the one storey eccentricity reinforced concrete frame and gives the way of impairing the torsional response through adjusting longitudinal reinforcement ratio.The model consided stiffness-deteriorating characteristics is built up with ANSYS program,to give a reference to the research of related problems of similar projects.

关 键 词：偏心结构 地震反应 扭转振动 纵向配筋率
